 - `Message Attachments <https://developers.mattermost.com/integrate/reference/message-attachments/>`_: Present rich, structured summaries such as status, priority, fields, links, or images for faster triage and comprehension. (Slack‑compatible schema.)
 - `Interactive Messages <https://developers.mattermost.com/integrate/plugins/interactive-messages>`_: Make notifications actionable with buttons or menus such as Acknowledge, Assign, or Escalate that enable an immediate user response without switching tools or context.
-- `Interactive Dialogs <https://developers.mattermost.com/integrate/plugins/interactive-dialogs/>`_: Guide users to successful outcomes when interactions need structured input or confirmation (for example, “Acknowledge with note” or “Assign to user”). Improve data quality with required fields, minimum/maximum input lengths, server‑driven user/channel pickers, validated defaults, inline field errors, placeholders, and help text that help users enter the right data the first time.
+- `Interactive Dialogs <https://developers.mattermost.com/integrate/plugins/interactive-dialogs/>`_: Guide users to successful outcomes when interactions need structured input or confirmation (for example, "Acknowledge with note" or "Assign to user"). Improve data quality with required fields, minimum/maximum input lengths, server-driven user/channel pickers, validated defaults, inline field errors, placeholders, and help text that help users enter the right data the first time. From v11.6.0, ``DateTime`` fields support two additional options: a configurable display timezone using an IANA timezone name (such as ``America/New_York``), which labels the picker with the configured timezone, and optional manual time entry so users can type exact times instead of selecting from preset dropdown intervals.
 - `Message Priority <https://developers.mattermost.com/integrate/reference/message-priority/>`_: Set ``priority`` to elevate critical posts and optionally request acknowledgements or persistent notifications.
 
 .. tip::
 
     - Need a dedicated identity, permissions scoping, or need to post outside of webhook/command flows? Use a `bot account <https://developers.mattermost.com/integrate/reference/bot-accounts/>`_ if you need a more permanent solution than using overrides for simple branding.
-    - If your system later needs to call Mattermost APIs (e.g., post follow-ups, open dialogs), authenticate with a bot user `personal access token <https://developers.mattermost.com/integrate/reference/personal-access-token/>`_. We recommend avoiding human/System Admin personal access tokens for automations and rotating and storing tokens securely.
